PROCESS OF GENERATING GAS.

SPECIFICATION formingpart of Letters Patent No. 278,145, dated May 22, 1883.

I Application filed November 4, 1882. (N model.)

To all whom it may concern:

Be it known that I, ERAZM. J. JERZMAN- OWSKI, of the city, county, and State of New York, haveinvented a new and useful Improvement in Processes of Generating Gas, of which the following is a full, true, and exact description, reference being bad to the accompanying drawing.

This inventionrelates to an improvement in the method of producing hydrogen gas, patented to G. M. Tessie Du Motay. In said process a lime-chamber is used, in which steam and naphtha vapor are converted in the presence of hot lime, the lime in said chamber being heated by combustible gases produced in independent retorts from coal. By my improvement I am enabled to dispense with said independent gas-generator for heating thelj me in the generator, and am enabled to utilize the same pipes and connections for heating the I generator, and for supplying the material to be converted into gas.

Theinvention will be clearly nn derstood from the accompanying drawing, in which A represents the generator, filled with lime, as described in said Tessie Du Motay patent. B represents the pipe through which the hydro gen gas produced is to be delivered; 0, an escape pipe or chimney. D, E, and F represent pipes for supplying steam, air, and naphtha, respectively.

Assuming the lime'to be heated, the valves in pipes D and F will be open, thereby injecting steam and any liquid hydrocarbon--such as petroleum, naphtha, &c.-upon the hot lime, whereby the same are decomposed, resulting in the production of hydrogen gas, which will pass through pipe B, to be treated in subsequent operations. After the lime has been cooled below the point at which conversion occurs, the valve in pipe B'is closed, and a valve in chimney 0 opened. Then, air being admitted through pipe E, a combustion will occur of the steam, air, and naphtha, or other hydrocarbon liquid, making an intense heat, and again raising the lime to the pointof conyersion. Of course if the lime were not sufficiently hot to light the injected steam, air, and hydrocarbon, a suitable apparatus should be provided for initiating their combustion, which would be the case when the lime was cold. By this process I greatly simplify the previous method and avoid the use of coal in the process, and I also get rid of the additional gas-generator. The effect also upon the lime of this combustion is much superior to the eftectproduced by water-gas, because no sulphuric impurities are driven upon it, and

quent injection of steam and naphtha is purer.

It is obvious that some other arrangement besides that of the pipes D, E, and F might be employed, and also that steam need not necthough I prefer to'do so.

What I claim as my invention, and desire to secure by Letters'Patent, is-

The process of producing hydrogen gas, which consists in subjecting steam and liquid hydrocarbons to contact with a heated body of lime until said lime has become cool, and in then heating said lime by the combustion of steam, liquid hydrocarbon, and air, substantially as described.
